What are some best practices for managing timestamp data in PHP and MySQL for time-sensitive operations?

When managing timestamp data in PHP and MySQL for time-sensitive operations, it's important to ensure that the timestamps are stored and compared accurately. One best practice is to use the MySQL DATETIME data type for storing timestamps, as it provides a precise representation of dates and times. Additionally, when working with timestamp data in PHP, it's recommended to use the DateTime class to handle and manipulate timestamps effectively. 

// Storing a timestamp in MySQL using DATETIME data type
$timestamp = new DateTime();
$timestampFormatted = $timestamp->format('Y-m-d H:i:s');
$query = "INSERT INTO table_name (timestamp_column) VALUES ('$timestampFormatted')";
$result = mysqli_query($connection, $query);

// Comparing timestamps in PHP using DateTime class
$timestamp1 = new DateTime('2022-01-01 12:00:00');
$timestamp2 = new DateTime('2022-01-02 12:00:00');

if ($timestamp1 < $timestamp2) {
    echo "Timestamp 1 is earlier than Timestamp 2";
} else {
    echo "Timestamp 2 is earlier than Timestamp 1";
}
